Charity of the Month
In December I am riding for Heifer International. Founded in 1944, Heifer International works with communities around the world to end hunger and poverty and to care for the Earth. Its approach is more than a handout. Heifer provides animals (e.g., heifers, goats, water buffalos, chickens, rabbits, fish, and bees) and training to impoverished people in over 30 countries. The animals can give milk, meat, or eggs; provide draft power; or form the basis of a small business. Communities make their own decisions about what crops, animals, and market strategies make sense for their everyday conditions and experiences.
Heifer International is based on 12 Cornerstones, such as Sustainability; Genuine Need and Justice; and Gender and Family Focus. Perhaps the best known Cornerstone is Passing on the Gift, in which Heifer recipient families pass on the offspring of their animals to others in need. In this way, whole communities can raise their standard of living.
A donation to Heifer International also can make a wonderful alternative holiday gift. Instead of yet another sweater for Grandma that she really doesn’t need, why not donate a Heifer animal or a share of an animal in her honor? Does your child really need so many new toys? Instead of five new toys, give him/her three new toys and a Heifer flock of chicks. Heifer has honor cards to let your loved ones know of your gift on their behalf.
I have set up a Team Heifer page to support Heifer International through A Year of Centuries. My goal is to raise $500. Please make your donation through https://teamheifer.heifer.org/AYearofCenturies. If you would like more information about Heifer’s work, please visit www.heifer.org. Whether you give to honor a loved one or make a regular donation, thank you for taking steps to transform the world for the better.

Bats and Wind Energy
Wind-energy facilities on forested ridge tops in the eastern United States are particularly dangerous to bats. The highest rate of bat fatalities usually occurs from late summer through fall, particularly on warm nights with low wind speeds. Peak fatalities for many bat species occur during the fall migration and mating season.
The best way to prevent these bat fatalities is to avoid building wind-energy facilities at high-risk sites. Once a facility is built, the most effective way to protect bats is to stop turbine blades from spinning during predictable, high-risk periods, e.g. when wind speeds are low. By raising the cut-in speed of turbines (i.e., the wind speed at which turbines begin generating electricity) and feathering blades below cut-in speed, bat fatalities can be reduced by up to 93% with only marginal losses in total annual energy production. Acoustic deterrents to minimize bat/turbine interactions also have shown promise, but additional research and development are needed.
Bat Conservation International (BCI) joined with the U.S. Fish & Wildlife Service, the American Wind Energy Association (AWEA), and the National Renewable Energy Laboratory (directed by the U.S. Department of Energy) to create the Bats and Wind Energy Cooperative (BWEC) in 2003. This alliance of non-profit, government, private, and academic organizations is working diligently to eliminate bat fatalities from wind turbines.
We humans have a responsibility to meet our needs in a way that is compatible with bats and all other living creatures.
